SPECIFICATION forming part of Letters Patent No. 273,839, dated March 13, 1883,

(No model.)

To all whom it may concern:

Be it known that I, THOMAS HENNEssY, of Oakland, county ot' Alameda, State of Cali.- fornia, have invented an Improved Stop- Valve; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in valves for water-closets, basins, 85e., and it is more especially applicable to a device for which Letters Patent were issued to me November 18, 1879.

It consists of certain details ofconstruction, embracing an adjustment of the spindle to regulate the opening ot' the valve, a removable valve-seat, and a valve-seat chamber made independent ot' the upper part of the cook, a spring to hold the valve to its seat, and a transparent chamber through which to inspect the interior, all of which will be more fully explained byreference to the accompanying drawings, in which- Figure l is a vertical section. Fig. 2 shows the lower portion removed. Fig. 3 is a view of the valve-seat.

In my former patent the valve-chamber, valve-seat, and valve were situated within the body of the cock, above its connection with the supply-pipe, and it was necessary to take the whole device in pieces to get at it. The stem or spindle by which the valve was depressed was also constructed to move a tixed distance, and would not limit or regulate the opening of the valve except to the amount for which it was originally set.

In my present invention, A is the cock or faucet as it appears above the marble of a wash-stand, and B is the dischargepipe or bib.

C is a screw-extension passing through the top of the wash-stand, and D a nut to beset up beneath, so as to secure it rigidly in place.

The upper part, E, of the valve-chamber is screwed upon the lower end of the extension O, and the valve-seat Fis iitted into it, so as to be removed and renewed at pleasure without disturbing this part E of the valve-chamber.

The lower part, Gr, of the valve-chamber fits into or against the upper portion, as shown,

and may be secured to it by bolts passing through anges H.

The valve I is of similar construction to that shown in my former patent, and closes the wa. ter-passage by rising against the seat F. It is opened by means of a stem, J, which extends down through a stuffing-box in the topI of the cock, and when it is forced down its lower end presses upon the top of the valve and forces it away from its seat. A spiral spring, K, surrounds its upper part and returns it to its place when released.

In order to regulate the amount of opening which shall be given the valve, a screw-th read is cut upon the top of the spindle J, and the knob L is screwed down upon it with a locknut, M, so that it may be fixed at any desired point. The bottom of the uut M strikes the top of the stufiing-box when the stem is depressed, and thus limits the downward movement according` to the point at which it is set.

In cold weather, where the water must be shut oft' over night to prevent freezing in the cocks and pipes, the body of the faucet may have a glass cylinder, N, forming a part of it.

Then the water has been shut oli', it' the valve is allowed to drop, it may become slightly frozen or fast to the bottom, so that when water is again turned on it would/"not act. To prevent this I employ a light spring, O, in the chamber below the valve, and this spring exercises just sufficient pressure upon the bottom ofthe valve to keep it closed when the water is off.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The independent valve l, moving i'ieely in its chamber, and closing upwardly against the seat F by the pressure 'from below, in combination with the stem J, extending vertically downward through the cock to the top ot' the valve, and having the adjustable knob L, by which the opening of the valve is regulated, substantially as herein described.

2. The basin cock or faucet havingthe valve I, moving independently within the chamber E G, and operated by the stem J, as shown,

in combination with the removable valve-seat; moving the faucet, substantially as herein de- F, fitted into the paru E of the chamber, subscribed.

stantially as herein described. In Witness whereof -I have hereunto set my 3. The basin cock ox' faucet; A, with its screwhand.
